PIPE.

SPECIFICATION forming part of Letters Patent No. 682,470, dated September 10, 1901. Application filed October 1,1900. Serial No. 81,857. (No model.)

To al?, 'wh/0m zit -nmy cow/cern.'

Be it known that I, JOHN FnANc'Is KEN- NEFICK, a citizen .of the United States, and a resident of Cripplecrcck, in the county of 'lllellerand State of Colorado, bzr. invente@ .anew and Improved Pipe, of whlch the following is a full, clear, Iand exact description.'

This invention relates to a tobacco-pipe, the purpose of which is topi- Ovide n superior means for keeping the pipe sweet and clean and rendering thesmoke cool before it reaches the mouth of the smoker.

This spe'ciiication is the disclosure of one form of the invention, while the claims (leine the actual scope thereof.

Reference is to he had to the accompanyingr drawings, forming a part of this speciiication, in which similar characters of reference indi cate corresponding parts in all the views.

Figure 1-is a. sectional view of the invention. Fig. 2 is a. plan view with parts broken away. Fig. 3 is perspective View of the suppler'nentul bowl. Fig. 4 is a perspective view of the supplemental stem. Fig. 5 is `a sectional View, showing the smoke-cooling attachment. Fig. 6 is n. detail view of the coollng-coil, andlig. 7 is a section of the supplemental stein with the stepper therme for use in connection with the cooling-coil.

As shown in Figs. 1 and 2, the pipe has a bowla, a stem b, and a mouthpiece c, all of the usual construction, excepting that the e nipple c' of the mouthpiece is formed with a longitudinal slit c2, rendering' it slightly coinpressible, so that it may be forced into the mouthpiece and held therein by the spring force of the split nipple. Within the bowl a is seated a. supplemental howl d, formed,`

preferablypf metal and havin g its upper edge flush with the upper edge of the bowl a. To the upper edge of -the supplemental howl d is fastened in any suitable manner a flange d', which projects outward over the upper edge of the bowl .a and which is formed with a number of perforations, as shown best iu Figs. 2 and 3, which permit the air to circulate between the bowl a and the supplemeninl bowl d, it being understood that the walls of these two parts are `spaced apart, so as to form an :tir-chamber.

Thelower erdof the surremenfsl l-.,wl d,

in which bowl the tobacco is placed, is

yterior of said stern.

formed with a threaded nipple cl2, screwing l into the supplemental stem @and u bushing.;A

7i., litted into the supplement-al stem to thicken the saine. This stem c is in the form of a tube, fitting snugly, yet removably, within the bowl d und provided at its outer end with ailange e',whichlies ageinstthe end otthestem eand against which the end of the mcuthpiccec is pressed when the mouthpiece is in place, as shown in Figs. l and 2. The nipple c'-.ot the mouthpiece c is introduced into the supplemental stem e, as shown. It desired, the inner end of the supplemental stem e may be thickened or provided with a .reinforce-plato at the point where the nipple d enters the supplemental stem, which construction is illustrated in Fig. l and the purpose of which is to strengthen the supplemental stem at this point. With the arrangement shown the bowl d and stem e may be withdrawn from the pipe at any time to be cleaned, and thus the pipe may be kept free from accumulations of nicotin and other objectionable mattei'. The supplemental stem e, together with the nipple 12, forms a trap, preventing the saliva from entering' the bowl d, and by removing the supplemental stein e this accumulation of saliva may be readily disposed of.

In Figs. 5, G, and 7 I have illustrated en attachment by which the smoke is effectively cooled. According to this construction the supplemental stem ez is formed in two sections, as indicated in Figs. 5 und 7, and these sections are joined by a bushing h', which also serves to receive the nipple d of the supplemental howl d. The stem c is elongated, so as to form a space between the adjacent ends of the stem b and the mouthpiece o. In this space is placed u coiled tube f, which iits snugly around the supplemental stein e? and has its ends in communication with the in- Iluccd within the stem e, between the ends of the coll j', ls a. stoppreferablyin the form of a cylindrical metallic thimble with a closed end. This stopper forces the smoke to pass from the inner end of the stem ei into and through the coiled plpef and .thence back into the stem e2 at the opposite side ot the stopper, from which point the smoke enters'the mouthpiece in tno usual manner. The coi] j causes the smoke to be subjected to the cooling influence of the surrounding atmosphere, and when the smoke reaches the mouth of the smoker it is cooled considerably and will not hen burn the smoker. Owing the formation of the stem ezin two parts the outer. part may be withdrawn et will for cleaning, leaving in the pipe the inner part of the supplemental stem and the bushing h'.

Having thus described claim as new and desire to Patentl. A tobacco-pipe, having a, main bowl, a. supplemental bowl removably secured therein,'the adjacent walls of the main and supplementel bowls being spaced apart Vto form an air-chamber and a. perforate flange extend-ing betweenv the upper edges of the mnin and supplemental bowls.

2. A tobacco-pipe, having a main stem and a. main bowl, a supplem ental stem removably lltted within the main stem, and a supplemental bowl removably fitted within the main bowl and seperated from the inner wall thereof, the base of the supplemental bowl 4being .joined to the supplemental stem end the supmy invention,- I secure -by Letters vsaid supplemental bowl plemental bowl having communication with the interior of the supplemental stem.

3. A tobacco-pi e having' a bowl, a, supplemental bowl fitte therein and spaced therefrom throughout its entire length to form an air-chamber, and a. flange carried by the upper edge of the supplemental bowl and extending outward over the upper edge of the mein bowl, the flange being perforated at points between the two bowls to open the said air-chamber to the atmosphere.

4:. A tobacco-pipe, having e main stem, a main bowl, a supplemental stem removably fitted within the main stem, und a supplemental bowl removably tted within the main bowl and being fastened to the supplemental stem et the base oi' the supplemental bowl,-

and stem having iuterior communication with each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
